When my gearbox gets hot, like when i'm out mapping and taking the car to the limiter etc.. it becomes really hard to come out of gear and into gears, when it's cold all changes are really nice and smooth!
I bought it having only done 1000miles since a rebuild and I have done another 1000miles myself so it's still pretty fresh!

Am I using the wrong oil or is this a symptom of a shit box, anyone else have this happen?

Cheers!
